The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.

Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.

Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

Shipping Weight

The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width &amp; height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

Vitamin D3 (cholecalciferol) is a nutrient that is critical to many bodily functions. Vitamin D3 is beneficial for supporting bone health, immune wellness, cardiovascular function, and cellular metabolism, among others. Mounting research is highlighting the ever-increasing benefits of optimal vitamin D3 status. Vitamin D3 is known to interact with over 200 different genes and thus plays a crucial regulatory role as a metabolic activator for a multitude of metabolic processes.

D3 Excellence

The recent research emphasis on the role of D3 supplementation has made this an essential part of my supplementation program. I would not want to be without my D3 even in the summer time when the sun is at its highest as I am a senior and have learned that my ability to convert sunshine to vitamin D has decreased over the years. Also, my dermatologist is constantly warning against sun exposure.

Had to stop taking D3

as any D3 supplement I take in any form after a while cause extreme kidney pain and excessive urination not sure why I have this reaction as I also take magnesium which is mean't to combat any problems but have heard of others that have this too, possibly a reaction to the lanolin which is derived from sheep. So be aware when taking D3 supplements if you start feeling this, as the pain is dreadful especially at night when trying to sleep and takes a while to go even after stopping the supplements.
